17 Introduction

Space Vector Modulation (SVM) is an improved technique for generating a fundamental sine wave that provides a higher voltage to the motor in a 3-phase system, lowers total harmonic distortion, and controls the number of short pulses in the Pulse Width Modulation (PWM) waveform.

Summary

Core VersionThis document applies to Space Vector Modulation v4.2.
Supported Device Families
  • PolarFire® SoC
  • PolarFire
  • RTG4™
  • IGLOO® 2
  • SmartFusion® 2
Supported Tool FlowRequires Libero® SoC v11.8 or later releases.
LicensingComplete encrypted RTL code is provided for the core, enabling the core to be instantiated with SmartDesign. Simulation, Synthesis, and Layout can be performed with Libero software. SVM is licensed with encrypted RTL that must be purchased separately. For more information, see SVM.

Features

SVM has the following key features:

  • The Min-Max method is implemented
  • The third harmonic voltage is generated from the min. and max. values of instantaneous 3-phase reference voltages
  • The third hormonic phase voltages are computed

Implementation of IP Core in Libero Design Suite

IP core must be installed to the IP Catalog of the Libero® SoC software. This is installed automatically through the IP Catalog update function in the Libero SoC software, or the IP core can be manually downloaded from the catalog. Once the IP core is installed in the Libero SoC software IP Catalog, the core can be configured, generated, and instantiated within the SmartDesign tool for inclusion in the Libero project list.
